OIL-BURNER ATTACHMENT F011 W001 OR COAL S'IOVESL mes es.

Application filed March 1.

To all whom it may concern Be it'known that I, FRANK AQSNIDEMAN, a citizen of the United States, residing at South Haven, county of Van Buren, State of -Michigan, have invented certain new and useful Improvements in Oil-Burner Attachments for Wood or' Coal Stoves, of which the following is .a specification.

This invention relates to improvements in oil burner attachments for wood orcoal stoves." p V The mainobjects of this invention are: First, to provide an oil burner attachment adapted for wood or coal stoves which is simple and economical to install and is very eflicient and also one which is very convenient to use. Second, to provide a structure of the" class described which may be quickly converted into a fire starting device when the stove is used as a coal or wood stove.

Further objects, and objects relating to structural details, will definitely appear from the detailed description to follow.

I accomplish the objects of my invention by the devices and means described in the following specification.

The invention is clearly defined and pointed' out in the claims. A structure which is-a preferred embodiment of my invention is clearly illustrated in the accompanying drawing, forming a part of this specification, in which:

Figure I is a detail plan view of a cook stove having my improvedoil burners installed therein, the stove parts being shown mainly in conventional form and with parts broken away to better show structural details. 'Fig. II is an enlarged detail view, partially in vertical section, on a line corresponding to line 2 2 of Fig. I. Fig. III is a detail view, partially in vertical sec-- tion, of a heating stove embodying the features of my invention. Fig. IV is a perspective view of one of my improved oil burners removed from the stove. Fig. V is a similar detail perspective view of one of my improved burners modified as a starting or kindling burner for coal or wood stoves. Figx VI is a detail verticalsection on a line corresponding to line 66 of Fig. V.

In the drawing, similar reference characters refer to similar parts'throughout the several views, and the sectional views are Specification of Letters Patent.

taken looking in the direction of the little arrows at the ends of the section lines.

Referring to the drawlng, 1 represents the top of a cooking stove. 2 one of the side walls thereof. 3 the fire pot, and 4 the grate. These parts are shown mainly in conventional form as the structural details are unimportant, 'my. improvements being adapted for embodiment in a variety of stove structures. j

Iprov'ideablock-like burner body 5, preferably a casting, having a fuel passage 6 therein to which the supply pipe 7 is connected,

the pipe being threaded into the burner body. This pipe leads from the fuel supply tank or reservoir 8, which is supported in a convenientposition so as to feed by gravity. Thelpipe'? is disposed through the sidewall 2 .of th'e st'ove and fire pot 3. The pipe is controlled by the valve" 9, while the flow of fuel or feed iscontrolled by the needle valve 10. The burner'tube 11, in

the structure illustrated, consists of a pair of coils disposed vertically side by side and terminating in a tip 12 disposed laterally within and at thebottom'of the coils. The tip 12 is provided 'With a jet orifice'13. The burner tube 11 is providedjwith a threaded nippleportion l4 threadedi'n'to the body member 5. so as to communicate with its assage 6. g I preferably provide a filterp15'which consists of a" short section of twisted wire cable disposed within the tube at its inlet end. I find, in practice, that this filter is not likely to clog and at the same time it is very durable and 'is' effective inpreventing any substance reaching the burner tip which would be likely to clog gthe delivery orifice 13 thereof. 1

. I preferably provide a circular deflector plate 16 having a projecting car 17 on its upper side perforated to receive one of the coils,"the perforationjbeing of such size that the deflector may be readily adjusted to the,

"desired position on the coil to deflect the The burner body member 5 is provided with recesses 18 on its upper side adapted to serve as starting cups. These recesses are preferably filled with asbestos, sand or ashes, indicated at 19. In starting the burner the valve 9 is opened long enough to allow a quantity of the oil to fiow from the burner tip opening 13 down onto the body member and into the starting cups. When a sufiicient quantity has been discharged the valve is closed and the oil lighted. This heats the burner tube above so that when the oil, which has been permitted to flow from the orifice, is consumed, the oil may be turned ,on again and is vaporized in its passage to the discharge orifice 13 so that it issues as a gas. After being started the coils are heated so as to thoroughly vaporize or gasify the fuel.

My improved burner'is very efficient and at the same time is very economical in fuel consumedwhen compared with the resulting heat units.

In the structure shown in Fig. I I provide a pair of the burners, arranged one below each lid, the burner body members 5 being connected by a pipe 20 controlled by the valve 21. My improved burner may be placed upon the grate in a cooking or heating stove without packing the grate as is customary in oil burning attachments, that is, it is usual practice to cover the grate with ashes, asbestos, sand or the like. My improved burner, however, does not necessitate this. A further advantage is that fuel is consumed without objectionable deposits of carbon within the fuel place or upon'the receptacles heated.

In the modification shown in Fig. III the burner is placed centrally within the fire pot 22, the pipe 23 being arranged through the wall of the stove substantially as is done when the structure is applied to a cooking stove. When it is desired to use the burner body 5 as a means for kindling or starting a. coal or wood fire the burner tube 11 is removed and the nozzle 24 is substituted. This nozzle is a short piece of pipe closed at its upper end and threaded at its lower end to be threaded into said burner body. The nozzle has lateral perforations 25 which constitute jet orifices for the escape of the fuel from the burner tube 24. When it is desired to start a coal fire, for example, the coal is placed in the fire pot directly upon the burner thus modified and the oil is turned on and ignited. The burner may be allowed to burn until the coal is well started when it may be cut off.

I have illustrated and described my improvements in the form in which I have embodied the same in practice. I have not attempted to illustrate or describe various modifications or adaptations to the different types of stoves, as I believe the disclosure made will enable those skilled in the art to which my invention relates to embody or adapt the same as circumstances may require.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent, is:
